MADRID, Sept. 19 (Xinhua) -- The Spanish Primera Liga sees a true 'David and Goliath' clash when Xerez visits the Santiago Bernabeu stadium on Sunday evening.

    While Real Madrid was spending 260 million Euros on players such as Kaka, Cristiano Ronaldo and Karim Benzema, newly promoted Xerez lost half of its squad because of financial problems.

    Coach Jose Angel Ziganda began pre-season training with just 13players on the books.

    Xerez now have a squad filled with players who have arrived either for free or on loan, but defeats in its opening two games in the new category, hint that it is going to be a long season.

    Real Madrid meanwhile has begun with two wins as well as a 5-2 triumph in Zurich in the Champions League.

    Xabi Alonso is out for 10 days with a calf problem, while Christoph Metzelder will miss three weeks with a torn muscle.

    Madrid coach Manuel Pellegrini will look to rest some players and make full use of his squad.

    Sunday also sees Athletic Club Bilbao entertain Villarreal. Athletic has had a surprising start to the season with two league wins, while Thursday saw an impressive performance against Austria Vienna in the Europa League.

    All eyes will be on Athletic's 16 year-old forward Iker Muniain, although he may start the game on the substitutes' bench.

    Villarreal also won in Europe on Thursday, beating Levski Sofia1-0. They will be placing faith in Brazilian forward Nilmar.

    Another side in European action in the week - Valencia entertains Sporting Gijon. Valencia striker David Villa began his career at Sporting and says one day he wants to return, but with his side challenging in the top four, he will be on the lookout to add to his goals tally.

    Almeria will be looking to score its first goal of the season at home to Getafe, while finally recently promoted Zaragoza aims to recover from last weekend's 4-1 thrashing in Seville, when struggling Valladolid is the visitor.
